ELECTEICLIGHTING FIXTURE.

Specification of Letters Patent.

Patented Oct. 19,1915.

Application filed March 26, 1914. Serial No. 827,309.

To all whom it may concern:

Be it known that I, CARL A. BROWN, a citizen of the United States,residing at Fostoria, in the county of Seneca, State of Ohio, haveinvented certain new and useful Improvements in Electric-LightingFixtures, of which the following is a specification.

My invention relates to electric lighting fixtures and more especiallyto fixtures such as indirect or semi-indirect which comprise a bowl orother inclosure of relatively large diameter suspended from above.

The object of my invention is to provide an efiicient support for theinclosure which will allow the ready removal of same for the purpose ofcleaning, and also its ready replacement without disturbing the lamps.

A further object of my invention is to provide in connection with thesupport for the inclosure a simple supporting means for the incandescentlamps or other light source used inl connection with the fixture whichwill admit of convenient removal and adjustment.

According to my invention I provide a frame or ring which is adapted tobe placed within the upper rim of the inclosure. The said frame carriesa number of fingers which extend downwardly therefrom and which are ofsuch shape as to engage the rim of the inclosure. Means are providedwhereby the said fingers are movable and adjustable so that they may beloosened for the purpose of removing the inclosure. The said lingers areso fashioned that suspension means, such as chains, may be attachedthereto for the purpose of supporting the structure. This insures thatthe suspension chains will always have the same relative positions andobviates the necessity for rearrangement after removal and uponreplacement of the bowl. The frame also carries a series ,of lampsupports which are preferably removably attached thereto so that if itis desired to increase the number of such supports those already mountedon the frame may be readily rearranged. Provision is made whereby thepositions of the lamps may be adjusted with respect to the bowl. l

My invention-.will be more clearly understood by referring to thedrawing, in which- Figure 1 is a plan view of the frame and attachedparts constituting part of my invention, and Fig. 2 is a partialelevation showing the parts of the fixture.

In the drawing 10 is a ring or frame, preferably of metal. Attached tothe said frame and preferably disposed symmetrically with referencethereto are offset and upwardly extending lugs 11. Pivoted to the saidlugs are fingers 12 which are hook-shaped and extend downwardly withrespect to the frame 10. The lower ends 13 of the said fingers areshaped so as to conform to the rim of the bowl 14 so that when held inengagement therewith they will support the said bowl. The other ends ofthe fingers 12 consist of lugs 15 which extend over the frame 10 andwhich are provided with apertures to receive adjusting screws 16. Thesuspension means or chains 17 engage with the fingers 12 and serves tosupport the fixture from above, as from the ceiling.

It will be apparent that, when the fingers 12 are in the position shownin full lines in the drawing, in which position they are held by reasonof the fact that the adjusting screws 16 bear against the frame 10 andare so adjusted that the fingers 12 are forced against the bowl, thebowl will be held firmly by the suspension chains 17. When it is desiredto remove the bowl the adjust-- ing screws 16 are loosened which allowseach of the fingers to be swung to the position shown in the dottedlines in Fig. 2. The bowl may then be removed without disturb ing theframe 10 or they suspension chains.

ltemovably attached to the inner side of the frame 10A by means ofscrews 18 are a series of flexible straps 19 which carry attachments 20at the ends thereof for receivlnga socket or other supports for incandescent lamps. It will beappaent that by tapping holes in the frame' 10at the desired places that any number of lamps may be mounted and anydesired arrangement may be secured. It will also be apparent that theflexible straps 19 provide a convenient means for adjusting to a certainextent the pesiMI tions of the lamps with respect to the frame, andtherefore the bowl of the fixtn 2.

Various modifications of the stru' e disV closed will readily suggesttheinsei.es to those skilled in the art and are considered to comewithin the scope of my invention.

W hat I claim as new and desire to secure by Letters Patent of theUnited States, is :---V

1. A fixture-bowl support comprising an annular frame adapted to liewithin the upf upper edge of said bowl, fingers pivoted atA their upperportions to said frame and extending below the' saine, and adjustablemeans for holding said fingers in position for engaging saidfixture-bowl.

3. A fixture-bowl support comprising a frame, transversely extendingfingers pivoted to said frame and having apertured lugs extending fromthe ends thereof adjacent to said frame and adjusting screws extendingthrough said apertures and engagin g said frame to hold said fingers indesired positions.

4. In a` lighting fixture, a bowl support' comprising a frameLbowlengaging fingers mounted on' said frame and movable relatively thereto,.suspension means engaging said fingers and means independent of saidsuspension means for :adjusting the positions of said fingers relativeto said frame.

5. In a lighting fixture a bowl support comprising a frame, transverselyextending fingers pivotally mounted on said frame, suspension meansengaging said fingers and means independent of said suspension means foradjusting the positions of Said fingers relative to the frame.

G. In a lighting fixture, a bowl and a bowl support comprising a framelocated within said bowl, fingers movably mounted on said 8. Inalighting fixture, a bowl support; comprising a'frame adapted to beinserted within the said bowl, adjustable means Y mounted thereon forengaging the said bowl, and lamp supports also mounted upon said 'frameand extending inwardly therefrom.

9. In a lighting fixture, a bowl support comprising a frame adapted tobe inserted within the said bowl, adjustable means mounted thereon forengaging the said bowl, and adjustable lamp supports also mountedupon-said frame and extending inwardly therefrom.

10. In a lighting fixture, a .bowl support comprising a frame, meansmounted thereon for engaging a bowl and flexible straps having lampattachments thereon extending inwardly rom said frame.

In wi ness whereof, I have hereunto set my hand this 16th day of March,1914.
